'UNITED STATES PATEEjT OErrcEn GEORGE A. SWARTZ, OF TWIN GROVE, WISCONSIN.

IMPROVMNT IN WINMILLS.

Specification forming part of Letters Patent No. 137,111, dated March 25, 1873.

To all whom it may concern:

Be it known that I, GEORGE A. SwARTz, of Twin Grove, in the county of Green and State of Wisconsin, have invented certain new and useful Improvements in Windmills; and I do hereby declare that the following is a full, clear, and exact description thereof, that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing and to the letters of reference marked thereon, which form a part of this speciiication.

The nature of my invention consists in the construction and arrangement of certain devices for throwing the wheel of a windmill out of the wind, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure 1 is a side view, and Fig. 2 a plan view, of my invention.' Figs. 3, 4, 5, 6, and 7 are enlarged detached views of various parts of the same.

A represents the usual turn-table of a windmill provided with the vane or wind-board B. This turn table is also provided with two horizontal arms, O and D, the former extending in a direction opposite to that of the vane B, while the latter extends at right angles therewith, as shown particularly in Fig.3. The turn-table A is further provided with an interior collar or ring, E, which is capable of turning within and independent of the turntable, and will also turn with the same. This collar or ring E is provided with a frame, G, extending horizontally and resting upon the upper surface of the turn-table. The frame G supports the horizontal shaft H, which has at its outer end the ,wind-wheel I, constructed in any of the known and usual ways, and at its inner end the usual mechanism for connecting it with the pump or other machine to be operated by it. To` the outer end of the frame G are attached two ropes, a and b. The

rope t passes around a pulley, el, in the outer end of the arm D, and then over a pulley, e, attached to a frame, j', on the turn-table so that the rope will pass down in the center.

The rope b in like manner passes around a pulley, el', in the arm O and pulley e in the frame f. By pulling on the rope afrom below the ring E with the frame G will swing and carry the wheel out of the Wind; and by pulling on the rope b the wheel will be brought into the wind again.

For pumps to fill a tank the movement of throwing the wheel out of the wind may be performed automatically by the following means: The rope a, after passing downward over the pulley e, as above described, may be passed over suitable pulleys so as to 'come per pendicularly down, and attached to a heavilyweighted lever, J, pivoted at its l other end. The weighted end of this lever, being raised, is supported on a hook, h, which is pivoted on the side of the tank K. In this tank is a lid, L, provided o n top with a.projection, t'. As the tank lills with water from the pump this lid rises and the projection t raises the inner end of a lever, P, also pivoted on the tank, and the outer end of which bears against the upper ,end of the hook h. When the tank is full the hook h will have been moved sufficiently'to release the weighted lever J, which, falling, pulls the rope a so as to throw the wheel out of the wind, as above set forth.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is-

l. In a windmill, the arrangement of the wheel and shaft upon a separate fra-me swinging upon and independent of the turntable carrying the vane, substantially as and for the purposes herein set forth.

2. The combination of the turntable A, with vane B and arms O D, ring or collar E, with frame G, carrying the shaft H and wheel I, ropes ,a 1), and pulleys d d and e e', all constructed and arranged to operate substantially as and for the purposes herein set forth.

3. The combination of the tank K, lid L, with projection t', leverd?, hook h, and weighted lever J, all substantially as and for the purposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 26th day of August, 1872.

Witnesses: GEORGE A. SWABTZ.
